Nikkei: KDDI plans 220 Mbps cellular network upgrade for summer 2014

KDDI au concept phones invade CEATEC

We already caught sight of KDDI au's cellphone as musical instrument concept devices last month, but it looks like the company's fanciful design group had plenty more than those to show off at CEATEC, as evidenced by Akihabara News' slew of pictures from the show. Those include the satellite-like device pictured above, as well as a neat little minimalist number pictured after the break and another folding contraption (also after the break) that we're still trying to wrap our heads around. Hopefully we'll get a chance to check these out ourselves before CEATEC wraps up but, until then, you can hit up the read link below for some more pics.
